ABSTRACT:
A tray formed from a unitary paperboard blank. The tray has at least one pair of parallel troughs whose ends are closed by end forming flaps carried by the trough bottoms. A longitudinal arch in the general form of an inverted V in transverse cross section separates the troughs and forms one side of each. The uppermost portions of the ends of the arch extend through the ends of the tray. In one embodiment, the top of the arch is sharp in transverse cross section, while in a second embodiment, the top of the arch is truncated. In the third embodiment, the tray has three parallel troughs.
